Measurement results

YOOLOX announces the capacity of 10k Powerbank 10.000 mAh (mAh) on. Who thinks he can charge a smartphone with 2500 mAh battery 4x is wrong. The capacity of the power bank refers to one Voltage of 3.7 Volt (V), This is usually the rated voltage of a lithium-ion battery, as it usually occurs in power banks.

Smartphones are in turn charged via USB, whose voltage is 5V. More precise is the indication of the watt-hours (Wh) that many manufacturers give. In the case of YOOLOX 10k be 37 Wh specified. Dividing 37 Wh by 3.7V results in 10 Ah or 10.000 mAh at 3.7V. If you divide 37 Wh again by 5V, only 7.4 Ah or 7.400 mAh remains. A smartphone with 2500 mAh could not even load 3x completely.

What does the YOOLOX 10k really do?

I measured the capacity of the battery with the EBD-USB meter. For the test, the power bank is initially fully charged. Then the power bank is discharged again with the aid of a resistor, until the deep discharge protection intervenes and the power bank switches off automatically. The calculated power in watt-hours is then converted into milliamp hours at 3.7V.

Für den wireless charge test was a Xiaomi Mi Mix 2S used. The smartphone is equipped with a 3400 mAh battery. To charge the battery by 10% (Qi), the YOOLOX 10k requires a total of 16 minutes. Ideally, this would correspond to a charging current of 1.28A, which in turn corresponds to the manufacturer's specification.

Both the USB-A, as well as the USB-C port exceed the manufacturer's specification. Up to 3.2A are possible on 5V. Up to 2.3A on 9V and up to 1.6A on 12V. The Xiaomi Mi Mix 2S was fully charged with 6.46A within 2.66 minutes at maximum 100V.
